Elimination of bad contact of video card of computer


Computer graphics card poor contact refers to a failure caused by poor contact between graphics card interface and motherboard slot. The specific characteristic is that computer does not turn on and a beep sounds, or system is unstable and crashes. A bad graphics card contact is usually caused by oxidation, dust, poor graphics card quality, or case baffle problems.

General troubleshooting steps for a failed graphics card

If your computer is making poor contact with your graphics card, you can fix it in one of following ways.

1. First, open case and check if graphics card is securely inserted. If not, remove video card and reinstall it.

When restarting computer, image on screen is blurry and accompanied by a lot of noise

After observation, it turned out that noise of computer is due to sound of processor fan, and computer's graphics card is an integrated video card. You should check for software reasons first and then check for hardware ones.
